If it is recirculating there is often a physical barrier to the vent hole that needs to be in place for the recirculation to work.

Does the hood suck anything e.g. a sheet of paper held underneath it?

If the hood had been installed at proper height (600 for electric, 650 for gas) and is properly ducted (or set up for recirculation) then you should notice it sucking up a fair bit if not all of steam being produced underneath it.

If all installation is correct then the next thing to check is the filters - are they correctly seated (and clean?)

I am not sure whether it is ducted or circulated.
As far as I remember, the guys who installed the rangehood just screwed the rangehood to the cabinet. I don't think that there was any duct. Maybe the duct was inside the cabinet?

Anyway, the filters (they look like 2 screens) are brand new and clean. The rangehood does not suck at all (even at 1 cm distance).

The supervisor recommended to contact Blanco (the manufacturer) to sort the problem out. However, as you said, if it is not installed properly then this is not blanco's problem, I think.

No it is not normal.

Is it a new installation?

Is your range hood ducted or re circulating?

1) Hood is trying to vent through a hole that is not there.
You need to confirm whether this is the case by looking inside the cabinet above the hood and seeing if there is a duct or chimney like buildout inside the cabinet.
If there isn't any, then it may be that your hood was installed for recirculation but has not been set up for it.
As said before there are often extra hardware inclusions that change a hood setting from vent to recirculate - others have a manual switch, it depends on the brand.
Your product documentation should contain details about this.

2) The hood is faulty.

Who supplied the appliances?
If they are part of a package provided by the kitchen fabricator or the builder then they should be checking this out for you.

If you supplied the appliance then your first stop should be talking to the boys who installed it.

Do you have site access? If so then either of these parties should be able to at least talk you through a quick check over the phone to establish any possible basic issues.

You could also contact Blanco and get their recomendation for establishing whether this is an installation or product fault issue - but it might be a bit hit/miss getting to talk to someone who can actually do this for you.

what brand is your rangehood? does your slide out rangehood has venting holes at the front of the unit just behind the front strip, like the Omega one shown below? I think only Omega, Robinhood, Blanco and Ariston make front venting recirculating slide out rangehoods. If yours is not one of those then you'll need to release the air thru a piece of duct either back to the room (recirculating) or to outside (ducted). Like ⋅ Add a comment ⋅ Pin to Ideaboard ⋅ Share

sorry again, didnt read you guys posts thoroughly. yours is Blanco and if it's front recirculating one then the holes at the front must be blocked. see this link for instructions on the blanco front recirculating slide out rangehood:
